GAS BURNER.

Application mea January 9, 192s. serial No. 245,370.

This invention relates to an improved gas burner which is adapted to be used in connection with a heating plant or in any other location where it is customary to have a roun gas burner.

The objects of the invention are to provide a burner of this type which is eflicient in its operation, which may be economically manufactured and easily installed, and especially to provide improved means for adjusting the amount of air to be mixed with` the gas, as the `latter flows from the burner, so as to insure the most perfect combustion.

The speciic construction of the invention, and its mode of operation, will be more particularly described in connection with the accompanying drawing, which illustrates one embodiment thereof, and in whichy Figure 1 represents a plan view of the burner assembly.

Fig. 2 represents a side elevation thereof.

Fig. 3 is a vertical section taken substantially on the line 3-3 of Fig. 1.

Fig/1 is a vertical section taken substantially on the line l1 4; of Fig. 1.

Fig. 5 is a plan View of the burner cast.- ing, the connecting .studs being shown in section.

Fig. 6 is a bottom plan'yiew of the ad-y justlng cam plate, with the connecting studs shown in section. a

As illustra-ted in the drawing, the burner casting 10 is in the sha e of a ring which is cored outto provide or the flowA of gas, opposite sides of the ring being connected by a spider or web 11. This cast-ing is preferably provided with two inlets 12 and 13, respectively, disposed on opposite sides thereof and adapted to be connected to a gas supply pipe. The upper side of the ring 10 is extended upwardly to form an annularrshoulder or flange 14 through which are bored a pluralityof equally spaced outlet holes 15.

Located above the burner casting@ 10 is a baille 16, which tapers downwardly, merg ing into a cylindrical portion 17 formed with .wings or enlargements 18 located above the respective holes 15 and having vertical passageways 19 in alinement with these holes. The cylindrical ortion 17 of the baille extends downward y beyond the enlargements `18, as indicated at 20, and lits within an annular series of lugs or shoulders 21 formed on the inner face of the ring 10. Opposite sides of the extension 20 are connected by a spideror` web 22, which is directly above the spider or web 11 of the burner casting` 10 and is centrally connected thereto by a stud 23. Rotationalmovement of the baille 16 about the central stud 23 is prevented by a guide pin 24, which is secured in the web` 11 near one side of the burner casting and extends upwardly through the web 22.

The baille 16, with the wings 18,/is supported in properly spaced relation to the burner ring'V by means of an adjustable cam plate 25, which lits within the shoulders 21 and rests on the burner casting. The plate 25 is formed near yits periphery with downwardly disposed equally spaced cams 27, which may be stamped from the plate. These cams have similar inclined surfaces which are adapted to bear against seats 28 'formed on the burner casting 10 inside of the ring. The plate 25 lhas a handle 29 by means of which it may be partially rotated within the annular series of shoulders 21. This handle may be stamped from the plate 25, as shown in Fig'ure, leaving an opening 30 in the pla-te through which the stud 23 passes.

The various parts of the burner are held in assembled relation by the stud 23. The web 22 is formed with a shoulder 32 against which the flattened side 33 of the stud engages so that it may be positively held against rotation when the wing nut 34 at the lower end of the stud is tightened.

From the foregoing description it will be understood that in order to adjust the baille upwardly or downwardly it is only necessary to loosen the nut 34 and then by means ofl t-he handle 29 to artially rotate the plate 25'to the right or eft as the case may be..

The inclined surfaces of the cams 27 riding on the seats 28 determine the adjustment of the baille 16,'a11d regulate the amount of air which will be mixed with the gas at it passes upwardly from the holes 15 through the lues 19. When the proper proportion of air in y the fuel mixtureis obtained, the lbaille may be locked in` its properly adjusted relation vto theburner vcasting by tighteningthe nut 341 In adjusting and securin the parts of the burner ilassembled relatlon, the guide stud 24 always serves to maintain the lues 19 in proper alinement with the holes 15. The plate 25 is provided with an arcuate slot 36 to permit the relative rotational movement of the late about the stud 24.

. The 1tliurner is so constructed that it may be economically manufactured on a commercial scale. It is very easy to assembleand install in connection with a furnace or in any other place where a round burner is used. The operation of adjusting the burner to proper quantity of air in the mixture is very simple and the mixture will always be uniform in all parts of the burner. l

While we have shown and described in detail the various parts of the burner as they are at resent constructed, it is to be understood t at this has been done merely for the purpose of illustrating the principles of the 1nvention and that these details may be considerably modified without departmg from What we claim is 1.
